My favorite website, Consumerist.com, offers a great suggestion on how to get an upgraded boarding pass for Southwest Airlines that involves little to zero knowledge of Photoshop:
1) View your boarding pass in Firefox.
2) Click “File” then “Save Page As”. Choose the “Save as Type” as Web Page, Complete.

4) Open the saved page with any HTML editor. Change the boardingB.gif or boardingC.gif to your saved file.
5) Print out your modified boarding pass and bring it to the airport.
Unsure what Homeland Security makes of this traveler’s tip.
